摘要
目的分析比较新疆不同产地唇香草挥发油红外光谱,为其鉴定和质量控制提供依据。方法利用红外光谱、二阶导数光谱,对新疆18个不同产地唇香草挥发油进行特征峰的指认和对比分析,并进行聚类分析。结果通过特征峰峰形、峰位与峰强的对比,发现不同产地唇香草挥发油之间存在差异,聚类结果显示可将18个产地唇香草分为4类。结论该方法直观、简单、方便、快速,并结合聚类分析,为唇香草挥发油的鉴别和质量控制提供了依据。
Objective To analyze and compare the essential oil of Ziziphora clinopodioides Lam. from different regions in Xinjiang by infrared spectroscopy; To provide a reference for its identification and quality control. Methods Characteristic absorption peaks of Ziziphora clinopodioides Lam. essential oil from 18 regions in Xinjiang Uygur autonomous region were identified, compared and analyzed according to peaks＇ shapes, positions and intensities by infrared spectroscopy, second derivative infrared spectroscopy and clustering analysis. Results Differences exist in the characteristic absorption peaks according to peaks＇ shapes, positions and intensities. And then the samples from 18 regions can be divided into four categories. Conclusion This method was direct, simple, fast and convenient. Combining with clustering analysis, It could provide a reliable evidence for identification and quality control of Ziziphora clinopodioides Lain..
